\ ASSEMBLING OLA-1M1.

Application filed March 20, 1924.

To all whom it may concern:

Be it known that I, J OHN J. MGGUOKIN, a citizen of the United States, residing at Brooklyn, Kings County, New York, have invented certain new and useful Improvements in Assembling Clamps, of which the following is a specification.

My invention relates to clamps for use in assembling the parts of Ford engines; and

my improvements are particularly directed to the production of a clamp which will temporarily hold the manifold in a proper position relative to the engine block while it is being permanently secured in place.

As is well known to those familiar with the art when, for any cause, the manifold and carburetor have been detached from the engine block, and it is desired to reattach them, the carburetor being first and the manifold next put in their appropriate positions, the manifold, unless specially supported, is apt to fall away from the block and disarrange the parts before they can be secured in position. The object I have in view is to provide a readily applicable and detachable clamp which will retain the manifold in place while the securing clamps are being made fast.

In the drawings Fig. l is an elevation of my improved clamp, showing it applied to a manifold and engine block; Fig. 2 is a view of the clamp taken as looking to the left on Fig. 1. Similar reference numerals are applied to the same parts in both the figures.

A typical engine block is designated by 1, and its manifold by 2.

The clamp is formed of two sections pivoted together; the section 3 being extended in an arm provided with a flange 4 adapted to rest on top of the manifold and with a pair of arms 5-5 adapted to press against the side of the manifold, at sufficiently separated points to steady the clamp and prevent its wabbling.

To the inner end of the section 3 is pivoted a section 6, one end 7 of which is adapted to rest against the back of the engine block, preferably at a point where it is supported by a projection 8 on the block; and the other end of the member 6 is extended into a handle 9, brought approximately into parallel with the body of the section 3 and in sufliciently close proximity thereto so that Serial No. 700,602.

both the handle9 and the body of the section 3 may be grasped at the same time in the hand of a mechanic so that the jaws of the clamp can be separated by the arm 9 being drawn down toward section 3 by the contraction of the hand. The spring 10 interposed between the sections 3 and 6 normally presses the terminals of the clamp toward each other; and a thumb screw 11 is, preferably, threaded through the handle 9 so that it may be made to impinge against the section 8 and prevent the pushing down of the handle 9 and the release of the clamp.

In operation the thumb screw 11 is backed up through the handle 9 so as to allow the desired scope of movement of the handle, and the jaws of the clamp are spread apart by the contraction of the operators hand embracing the handle and the member 3.

The manifold having been placed in position and held there temporarily, as by the free hand of the operator, the clamp is then straddled over the block and carburetor in the position shown in Fig. 1, and the handle 9 is released, allowing the jaws to grip against the manifold and the engine block under the impulse of the spring 10. If it is desired to lock the clamp in this position, the thumb screw 11 may then be run down to press against the member 3 and prevent the opening of the clamp until the screw is backed off.

This arrangement securely holds the manifold in its proper assembled position until its permanent anchoring means are applied, after which the clamp may be released and removed.

Having thus described my invention, what I claim and desire to secure by Letters Pat ent of the United States is 1. In an assembling clamp for internal combustion engines, the combination of two pivotally connected members, one thereof be ing provided with integral means for engaging above a manifold and with integral means for engaging against the side of the manifold, and the other thereof being provided with means for engaging against the back of an engine block; elastic means for urging the jaws of the clamp toward each other, and means for locking the clamp in applied position.

2. In an assembling clamp for internal combustion engines, the combination of two pivotally connected members, one thereof being provided with integral means for engaging above a manifold and with integral means for engaging against the side of the manifold, and the other thereof being provided with integral means for engaging against the back of an engine block and with integral means for opening the clamp, con sisting of an extended handle, elastic means for urging the jaws of the clamp toward each'other, and means consisting of athumb screw threaded through the handle, for locking the clamp in applied position.
